Key information relevant to the recruitment process for the
overall study, such as dates of the recruitment period and locations

59 unique participants (par.) received >=1 investigational product (IP) dose; however, 1 par. was not given a randomization number and therefore was not enrolled into the study. Thus, the number of par. enrolled in the protocol record=58. 5/59 par. receiving only single doses of IP are not included in the Intent-to-Treat Exposed Population (N=54).

Pre-Assignment Details

Significant events and approaches for the overall study
following participant enrollment, but prior to group assignment

Per protocol, the initial intention was to enroll par. to receive fosamprenavir; however, ultimately, no par. were enrolled into cohorts to receive repeat dosing of fosamprenavir without ritonavir boosting. The 59 par. who received >=1 IP dose were included in the Safety Population.

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.
Also provides relevant details such as imputation technique, as appropriate.

Blood samples of participants were collected to assess the decrease in the number of HIV-1 RNA copies. Change from Baseline in plasma HIV-1 RNA was calculated as the value at the indicated time point minus the value at Baseline.

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts
the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release
and can embargo communications regarding trial results for a period that is less than or equal to 60 days.
The sponsor cannot require changes to the communication and cannot extend the embargo.

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release
and can embargo communications regarding trial results for a period that is more than 60 days but less than
or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.

Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.

Restriction Description:
GSK agreements may vary with individual investigators, but will not prohibit any investigator from publishing. GSK supports the publication of results from all centers of a multi-center trial but requests that reports based on single-site data not precede the primary publication of the entire clinical trial.
